Hinsdale – Adventist Hinsdale Hospital is among about 25 hospitals in the country where a new aneurysm procedure is being performed as an alternative to surgery. Dr. Victor Aletich, an endovascular neurosurgeon, has performed two embolization procedures using the Onyx Liquid Embolic System, which injects a precipitating liquid into an aneurysm to block blood flow into it and minimize the risk of rupture.
“This minimally invasive procedure allows appropriately selected patients to avoid surgery,” Aletich said. “Our neuro-endovascular team is proud to continue to offer the latest technological advancements in the Chicago area.”
The treatment is designed for patients with cerebral aneurysms classified as “wide-necked.” Cerebral aneurysms are vascular abnormalities in the brain that are characterized by a bulge in the wall of a blood vessel. These defects can cause severe neurologic symptoms, including death in the case of a rupture. Aneurysms can occur in various locations along the blood vessels of the brain.
Carole Einhorn, a 62-year-old retired educator from Buffalo Grove, researched several treatment options recommended by Aletich before deciding to undergo the Onyx procedure to treat her aneurysm, which was discovered incidentally during an MRI. She stayed in the hospital two nights following the procedure and was back on the treadmill four days later.
“You can’t beat that,” Einhorn said of her quick recovery following the May 30 procedure. “I felt very comfortable with my decision and was very pleased with Dr. Aletich. I felt that I was in good hands.”
Using the Onyx system, an embolization procedure takes a few hours and is done under general anesthesia. The patient lies on a table where special X-ray and monitoring equipment allows the physician to navigate catheters (thin tubes) to the aneurysm. The catheter is inserted through an artery in the upper leg and is guided into the aneurysm. After the tip of the catheter is placed within the aneurysm, a small catheter with a balloon at the tip is positioned along the aneurysm to seal the opening as the liquid Onyx is delivered into the aneurysm. The balloon catheter and Onyx delivery catheters are then removed. The U.S. Food and Drug Administration approved use of the Onyx device in 2007.
Endovascular coiling and surgical clipping of aneurysms are the most common current treatments for cerebral aneurysms and has been the standard treatment for many years. Coiling of aneurysms consists of placing a small catheter into the aneurysm, similar to the Onyx procedure, but instead of a liquid agent, platinum coils are placed in the aneurysm which promotes clotting within the aneurysm preventing rupture. Onyx provides an alternative treatment to coiling of an aneurysm, and has been developed to potentially improve the results of endovascular treatment of aneurysms.
